Muscle Grip Strength Lab Report

Skeletal muscle is a form of striated muscle tissue existing under the voluntary control of the somatic nervous system (Medscape 1). Skeletal muscle is part of the three big muscle types, it is connected to bones by tendons (Medscape 1). Muscle grip strength is significant to an individual because it helps the person know the ability of muscle power and force that they have in their hands. This will help notify the individual of what activities they can do or withstand. Provided each participant will be able to determine their grip strength in a seated and standing position, while being able to compare and contrast their results with the grip strength in the normal population.

Materials and Methods:
The demographics for each of the five participants were recorded which included thier initials, gender, age, height, weight, handedness, and whether or not the participant exercises regularly (using E for exercise and S for Sedentary). It was then jotted down of the date, time, location, and temperature of the room. Then the muscle grip strength test was conducted. One by one each participant would take turns using the dynamometer. Participants had to make sure that the dynamometer was calibrated to zero after each use. First using the right hand the participant would squeeze their hand while sitting, and then standing. The participant would then move to the left hand and repeat the task. This was repeated until all five participants had their turn and everyone had recorded the data.The independent variable for the this lab was the individual grip strength for all five participants. The dependent was the normal grip strength of the general population and the control entailed the dynamometer. Results:

These results were taken in room of 78 degrees, on the date of February 2, 2012, at 7:45 p.m. In the parker annex lab building.
